A pilot on a space ship moving at 0.86c away from the Earth sends a laser beam signal to Earth. (a) The pilot measures the speed v of the laser beam signal to be (A) v (C) v > c. (b) The people on Earth measure the speed y of the laser to be (A) v (C) v > c.
(a)The correct option is (B) v = c.A pilot on a space ship moving at 0.86c away from the Earth sends a laser beam signal to Earth. Light wave is an electromagnetic wave. Its value will be same irrespective of the frame reference. Therefore the pilot measures the speed v of the laser beam signal to be equal to the speed of light c. From the above observation we conclude that, option (B) is correct.(b)The correct option is (B) v = c.A pilot on a space ship moving at 0.86c away from the Earth sends a laser beam signal to Earth.
